SNOW-PLOW.

Specification of Letters Patent.

Patented Feb, 6, 1917.

Application filed June 18, 1916. Serial No. 103,503.

To all whom it may concern:

Be it known that I, MICHAEL M. DOMEK, a citizen of the United States, residing at Ivanhoe, in the county of Lincoln and State of Minnesota, have invented certain new and useful Improvements in Snow-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in snow plows and more particularly to that class adapted to be used for cleaning railway tracks of snow, and my object is to provide a mold board or plow structure which is adapted to throw the snow, and other obstructions to each side of the track way and out of the path of the train.

A further object is to provide means for attaching the plow structure to parts of the train.

And a further object is to provide cutting disks for macerating hardened snow where by it may be readily removed by the plow structure.

Other objects and advantages will be hereinafter set forth and more particularly pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure 1 is a side elevation of one end of a flat car showing my improved plow structure attached thereto.

Fig. 2 is a top plan view thereof, and

Fig. 3 is a transverse sectional view through the plow structure and a set of disks attached thereto.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a fiat car of the usual or any preferred structure, to one end of which is attached an angular frame 2 by means of brace bars 3 and 4:, the brace bars 3 resting upon the floor of the flat car, while the brace bar 4 is attached at one end to the lower face of the flat car and at its opposite end to the vertical portion of the angular frame adjacent its lower end. Attached to lips 5 and 6, at the free ends of the vertical and horizontal sections of the angular frame, is

a ridge bar 7 which is preferably triangular shape in cross section, the upper end of the ridge bar being reinforced by means of a brace bar 8, said brace bar 8 connecting at one end with the upper end of the ridge bar and at the opposite end with the brace bars 3.

Disposed over the ridge bar 7' is a mold board 9, said mold board having oppositely inclined faces 10 and 11, the forward ends of the faces being tapered to a point 12 which is in alinement with the ridge bar 7, while the rear ends of the faces are curved and serve to throw the snow, and the like, encountered by the mold board, to each side of the track way 13, upon which the flat car is traveling.

This form of plow structure is primarily used for removing snow from cuts along railway tracks, and as the snow frequently packs tightly and becomes hardened, I provide means for cutting or macerating the snow by placing upon the inclined face of the mold board any suitable number of cutting disks 14., said disks being rotatably mounted upon the plow structure in any suitable manner, as by extending stems 15 from the disks through the faces of the mold board and through substantially triangular shapc reinforcing members 16, below the mold board, said disks preferably resting at an angle to the inclined faces of the mold board, so that the edges of the disks at the point of contact with the snow will be a distance from the faces of the mold board thereby permitting the disks to more readily enter the snow and disinte grate the same, and as the disks rotate the snow will be prevented from packing between the disks and the faces of the mold board.

This device, while shown as attached to a flat car, may be attached to any suitable part of a car or engine and may be used for clearing electric railway tracks as well as the other forms of railway tracks.

It will likewise be seen that by providing the cutting disks and placing them at an angle to the trend of the faces of the mold board, snow encountered by the mold board will be thoroughly disintegrated or macerated so that it may be readily thrown to one side of the track way and out of the path of the car to which the plow structure is attached.

It will likewise be seen that the plow structure will be rendered extremely strong and durable in view of the manner in which the parts thereof are braced.

I claim 1. The combination with a car structure, of a frame attached to said car structure, said frame disposed in alinement with and inclined to the said car structure, a mold board having oppositely inclined faces mounted upon the inclined frame, and cutting disks rotatably mounted on said mold board at an angle thereto.

7 2. The combination with a car structure, of an inclined frame, brace bars connecting the frame with the car structure, a mold board attached to said inclined frame, said mold board having oppositely inclined faces, and a plurality of cutting disks rotatably secured to each face of the mold board in direct alinement, said disks being disposed at an angle to the inclined faces of the, mold board.

3. The herein described snow plow comprising an angular frame, a ridge bar attached to the free ends of the vertical and 1 horizontal sections of the angular frame, a mold board resting upon said ridge bar, re-

inforcing members below the mold board, means to attach the mold board to a moving vehicle, a plurality of cutting disks, and means to attach the cutting disks to the mold board whereby said disks will rest at an angle to the inclined faces of the mold board.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
